both are pretty go,but sometime it help to twist it up a bit.try not using any of the starters try a wild one,just the the first one you find.that'll make your game a little m tougher and teaches you to use different types than your use to.

Sceptile is the best all the way. sceptile may have more weaknesses but if swampert gets hit with one giga drain by a strong grass type and hes done for. My sceptile has taken a sunny day flamethrower before. He didnt have much health left but at least he was still going.
